Description
1 DESCRIPTION1 DESCRIPTION
La présente invention concerne le domaine des accessoires des machinesoutils, à commande numérique, centres d'usinage, cellules et ateliers flexibles et a pour objet un mandrin porte-fraise hydro-expansible. The present invention relates to the field of machine tool accessories, numerically controlled, machining centers, cells and flexible workshops and relates to a hydro-expandable milling cutter mandrel.
Les outils de fraisage ou fraises utilisés sur les machines susvisées se présentent généralement sous forme d'éléments sensiblement cylindrique montés par l'intermédiaire d'un alésage sur un moyeu de porte-outil et serrés sur ce dernier par l'intermédiaire d'une vis. The milling tools or milling cutters used on the machines referred to above are generally in the form of substantially cylindrical elements mounted via a bore on a hub of a tool holder and clamped on the latter by means of a screw .
Un tel mode de montage des fraises permet un serrage correct de ces dernières. Cependant, du fait de l'augmentation des performances des machines modernes et donc des vitesses de coupes élevées en découlant, la précision du montage de ces outils devient primordiale. Such a mounting mode of the cutters allows a correct tightening of the latter. However, because of the increase in the performance of modern machines and thus the high cutting speeds that result, the precision of the assembly of these tools becomes essential.
En effet, ce montage doit à présent être effectué de parfaitement centrée, ce qui est difficilement compatible avec le mode de centrage par simple ajustement actuellement mis en oeuvre. Indeed, this assembly must now be performed perfectly centered, which is hardly compatible with the centering mode by simple adjustment currently implemented.
La présente invention a pour but de pallier ces inconvénients en proposant un mandrin porte-fraise permettant un centrage et un serrage parfaits et reproductibleS de l'outil, sans adaptation spécifique lors des changements d'outils. The present invention aims to overcome these disadvantages by providing a milling mandrel for a perfect centering and perfect clamping and reproducibleS tool without specific adaptation during tool changes.
A cet effet, le mandrin porte-fraise conforme à l'invention, constitué par un corps de montage sur un porte-outil et muni d'un moyeu de fixation d'un corps de fraise, est caractérisé en ce que le moyeu de fixation d'un corps de fraise est hydro-expansible. For this purpose, the milling mandrel according to the invention, consisting of a mounting body on a tool holder and provided with a hub for fixing a milling body, is characterized in that the fixing hub a strawberry body is hydro-expandable.
L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels: la figure 1 est une vue en élévation latérale et partiellement en coupe d'un mandrin porte-fraise conforme à l'invention muni d'une fraise; la figure 2 est une vue en élévation frontale du mandrin seul, et la figure 3 est une vue en coupe suivant A-A de la figure 2. The invention will be better understood, thanks to the following description, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the appended diagrammatic drawings, in which: FIG. a side elevational view and partially in section of a milling mandrel according to the invention provided with a milling cutter; Figure 2 is a front elevational view of the mandrel alone, and Figure 3 is a sectional view along A-A of Figure 2.
Les figures 1 à 3 des dessins annexés représentent, à titre d'exemple, un mandrin porte-fraise constitué par un corps 1 de montage sur un porteoutil et muni d'un moyeu 2 de fixation d'un corps de fraise 3. FIGS. 1 to 3 of the accompanying drawings represent, by way of example, a milling mandrel consisting of a mounting body 1 on a tool holder and provided with a hub 2 for fixing a milling body 3.
Conformément à l'invention le moyeu 2 de fixation d'un corps de fraise 3 est hydro-expansible. A cet effet, le moyeu 2 présente un manchon extérieur 4 pourvu d'une chambre annulaire 4' à paroi extérieure de faible épaisseur, cette chambre étant reliée à un moyen 5 de mise sous pression, traversant le corps 1. In accordance with the invention the hub 2 for fixing a mill body 3 is hydro-expandable. For this purpose, the hub 2 has an outer sleeve 4 provided with an annular chamber 4 'with a thin outer wall, this chamber being connected to a pressurizing means 5, passing through the body 1.
Le fluide sous pression est avantageusement de l'huile et l'amenée de cette huile sous pression dans la chambre annulaire 4' du manchon 4 a pour conséquence, sous l'effet de la haute pression de l'huile injectée dans ladite chambre 4' de provoquer une déformation élastique de sa paroi extérieure qui est ainsi plaquée contre la paroi du perçage central de la fraise 3. The fluid under pressure is advantageously oil and the supply of this oil under pressure in the annular chamber 4 'of the sleeve 4 has the consequence, under the effect of the high pressure of the oil injected into said chamber 4' to cause an elastic deformation of its outer wall which is thus pressed against the wall of the central bore of the cutter 3.
Il en résulte, du fait de la répartition uniforme de la pression dans la chambre annulaire 4', une déformation régulière de la paroi extérieure délimitant cette chambre, de sorte qu'est effectué automatiquement le centrage de la fraise 3 sur le moyeu 2 du corps 1. La fraise 3 ayant préalablement été montée sur le moyeu 2 et en chevauchement des entraîneurs 1' du corps 1 avec un léger serrage de maintien par l'intermédiaire de la vis de serrage 7, il suffira, après mise sous pression de la chambre 4' de serrer à force la vis 7 dans le moyeu 2 du corps 1 pour fixer définitivement la fraise 3 sur ledit moyeu 2. As a result, due to the uniform distribution of the pressure in the annular chamber 4 ', a regular deformation of the outer wall delimiting this chamber, so that is automatically performed the centering of the cutter 3 on the hub 2 of the body 1. The cutter 3 having previously been mounted on the hub 2 and overlapping of the drivers 1 'of the body 1 with a slight clamping by means of the clamping screw 7, it will suffice, after pressurizing the chamber 4 'of tightening the screw 7 in the hub 2 of the body 1 to permanently fix the cutter 3 on said hub 2.
De préférence, le manchon extérieur 4 est une pièce rapportée fixée sur le moyeu 2 par frettage, brasage ou autre et le moyen 5 de mise sous pression est avantageusement relié à la chambre annulaire 4' par l'intermédiaire d'un perçage disposé, de manière connue, dans le moyeu 2 et débouchant à travers la paroi de celui-ci dans la chambre annulaire 4'. Preferably, the outer sleeve 4 is an insert attached to the hub 2 by shrinking, brazing or the like and the pressurizing means 5 is advantageously connected to the annular chamber 4 'by means of an arranged drilling, known way, in the hub 2 and opening through the wall thereof in the annular chamber 4 '.
Selon une autre caractéristique de l'invention et comme le montrent plus particulièrement les figures 2 et 3 des dessins annexés, le moyeu 2 du corps porte-fraise 1 est avantageusement pourvu, en outre, de perçages longitudinaux 8 s'étendant parallèlement à son axe dans le pourtour du moyeu 2 et débouchant sur sa face avant pour communiquer avec des canaux de lubrification non représentés prévus dans le corps de la fraise 3 pour déboucher près des plaquettes de coupe 3' de cette dernière, ces canaux longitudinaux 8 débouchant à leur autre extrémité dans une chambre 9 reliée à un conduit axial 10 d'amenée de liquides de lubrification. According to another characteristic of the invention and as shown more particularly in FIGS. 2 and 3 of the accompanying drawings, the hub 2 of the milling cutter body 1 is advantageously provided, in addition, with longitudinal bores 8 extending parallel to its axis. in the periphery of the hub 2 and opening on its front face to communicate with unrepresented lubrication channels provided in the body of the cutter 3 to open near the cutting plates 3 'of the latter, these longitudinal channels 8 opening to their other end in a chamber 9 connected to an axial conduit 10 for supplying lubricating liquids.
La chambre 9 peut, par exemple, correspondre à un évidemment réalisé dans le corps 1 proche de l'extrémité de la vis 7 de serrage de la fraise 3 lorsque cette dernière est serrée à fond. The chamber 9 may, for example, correspond to an obviously made in the body 1 close to the end of the screw 7 for clamping the cutter 3 when the latter is fully tightened.
Grâce à l'invention, il est possible de réaliser un mandrin porte-fraise permettant d'obtenir un centrage parfait de l'outil, de sorte que son réglage peut également être effectué de manière parfaite et reproductible sans adaptation spécifique à chaque outil. En outre, la prévision des canaux de lubrification en périphérie du moyeu 2 permet d'assurer une bonne alimentation de la partie avant de l'outil en fluide de lubrification. Thanks to the invention, it is possible to achieve a milling mandrel to obtain a perfect centering of the tool, so that its adjustment can also be performed perfectly and reproducibly without specific adaptation to each tool. In addition, the provision of the lubrication channels at the periphery of the hub 2 makes it possible to ensure that the front portion of the tool is properly supplied with lubricating fluid.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
